Water when the top inch of soil feels dry, usually 2-3 times per week. Keep soil consistently moist but never soggy. Reduce watering in winter when growth slows. Use room temperature water to avoid shocking the roots.

☀️ Lighting

Prefers bright, indirect light but can tolerate low light conditions. Avoid direct sunlight which can scorch the delicate fronds. East-facing windows or filtered light from south/west windows work best. Insufficient light may cause yellowing leaves.
